Abstract

This study was aimed to investigate potential of 15 endophytic bacteria (3C, AK, CH, GKSKK, GBSH, AM, B1, GKSKC, GBSK3, GKSKW, GKSKP, A31, GKSKKn, NS and AP) that were isolated from healthy leaves of pinneaple as plant growth promoter and antagonist of pineapple-fungal plant pathogens. The isolates were investigated on their hipovirulence, ability as plant growth promoter and ability to inhibit three pineapple-fungal pathogens, namely Phytophtora sp., Curvularia sp. and Thielaviopsis sp. The result showed that 10 out of 15 isolates were hipovirulent. Among 10 hipovirulence isolates, 7 isolates had potential as plant growth promoter (3C, AK, GKSKK, AM, B1, GKSKC and GBSK3). In the case of their antagonistic capability, the isolates which were produced the highest percentage of inhibition against Phytoptora sp. and Curvularia sp. were GKSCK at 72,48% and 66,08% of inhibition, respectively. Meanwhile, the highest percentage inhibition against Thielaviopsis sp. was obtained by CH at 64,82% of inhibition. In this study, we found that some of the endophytic bacteria can be plant growth promoter or antagonist or both as plant growth promoter and antagonist.
